Subject [users@httpd] Major Issue -- Apache not closing open requests
Date Fri, 18 Feb 2005 07:37:35 GMT
I run a fairly high traffic Web site on a dedicated Redhat 7.2 server 
(1.7Ghz proc, 512M ram).  Apache 2.0.48 had been running for about 35 days 
since it was restarted, no problems.

As of a few hours ago, Apache decided to start opening connections, but not 
closing them.  MaxClients was quickly reached, and the server stopped 
responding.  I restarted Apache, and the max request limit (which I upped 
to 256) is reached in under a minute.

 From the server-status page:Current Time: Friday, 18-Feb-2005 01:21:10 CST 
Restart Time: Friday, 18-Feb-2005 01:20:22 CST Parent Server Generation: 12 
Server uptime: 48 seconds Total accesses: 73 - Total Traffic: 546 kB CPU 
Usage: u2.68 s.58 cu0 cs0 - 6.79% CPU load 1.52 requests/sec - 11.4 
kB/second - 7.5 kB/request 256 requests currently being processed, 0 idle 

Here's the status page at the point I noticed the problem, before I 
restarted the server:Current Time: Thursday, 17-Feb-2005 22:02:49 CST 
Restart Time: Wednesday, 12-Jan-2005 21:40:11 CST Parent Server Generation: 
4 Server uptime: 36 days 22 minutes 38 seconds Total accesses: 17525775 - 
Total Traffic: 44.5 GB CPU Usage: u216.48 s38.59 cu1.44 cs.27 - .00825% CPU 
load 5.63 requests/sec - 15.0 kB/second - 2725 B/request 150 requests 
currently being processed, 0 idle workers 

My logs aren't showing anything abnormal, except for the fact that the 
server stops accepting connections after 1 minute (tried running with 
loglevel set to debug as well).  I compiled apache 2.0.53 hoping that would 
fix something, and am still having the issue.  "lsof" shows 256 unique IP's 
connected.  "ps auxf" shows 256 children. I have done all the 
troubleshooting I can think of (more than what I have listed here) and am 
really at a loss here.  Does anybody have any ideas?

Thanks in advance!
